After FW download is complete, the CTS line is already seen low. It becomes high after 2 msec, and low again after FW initialization is complete. This makes the current check for CTS low redundant. This removes the wait for CTS low section and increase delay to 1200msec instead, which is sufficiant for all NXP chipsets to initialize FW.
